[Zope] sql query results -> DTML method problem

[Lee Reilly CS1997]

Hi,

I have a TINY problem, which I think there is a simple solution too...
but for the life of me, I can't find it! I'd be grateful if someone
could point me in the right direction.

I have a database setup containing details of classes, students &
lecturers. The user is prompted to enter a class code (a unique key)
which is used to query the database and return the class title. Simple.

A DTML method prompts me for the class code
-- I enter 52.139 and it posts to a method 'enterClassCodeAction',
below.

#1 	<dtml-var standard_html_header>
#2 	<h2>Confirm</h2>
#3 	<p>You entered <i><dtml-var class_code></i></p>
#4
#5 	<p>
#6 	Our records show that <dtml-var class_code> is called
#7
#8 	<dtml-in expr="findClassTitle(code=52.139)">
#9 	<dtml-var title>
#10 	</dtml-in>
#11	
#12
#13 	</p>
#14 	<dtml-var standard_html_footer>

^ The method works fine when the class code is manually inserted (line
#8) but when I try to pass the variable from the previou post, held in
<dtml-var class_code> I have probs.

<dtml-in expr="findClassTitle(code=<dtml-var class_code>)"> *** syntax
error

findClassTitle is a ZSQL method for returning the class title given a
class code:
	
	select title from classes 
	where <dtml-sqltest code op=eq type=float>

Hmm... anyone see the problem?

Thanks a lot :)

- Best regards,

Lee
